The 1,600 hp (1,200 kW) FA-2/FB-2 (along with the FPA-2/FPB-2 variants) was built between October 1950 and June 1956. Finally, the 1,800 hp (1,300 kW) FPA-4/FPB-4 , powered by the 251 V-12 engine, was built between October 1958 and May 1959 by ALCO's Canadian subsidiary, Montreal Locomotive Works (MLW).

The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants.
A pair of ALCO PA-1s of the Santa Fe Railway in March 1968. There were two models of PAs: the 2,000 horsepower (1,500 kW) PA-1/PB-1, which was built between September 1946 and June 1950, and the 2,250 horsepower (1,680 kW) PA-2/PB-2, which was built between April, 1950 and December, 1953.

The model 251 engine design was initiated in 1949 and, like the 244 engine, it had a bore (cylinder diameter) of 9 inches (229 mm), and a stroke of 10.5 inches (267 mm). Its designation combines Alco 's identifier for that bore and stroke - 2 - with the year its design was approved for laboratory testing - 1951.
The ALCO RSD-1 is a diesel-electric locomotive built by the American Locomotive Company (ALCO). This model was a road switcher type rated at 1,000 horsepower (750 kW) and rode on three-axle trucks, having a C-C wheel arrangement. It was often used in much the same manner as its four-axle counterpart, the ALCO RS-1, though the six-motor design ...
Only four RSC-24s were built – all in 1959. [1] They were numbered 1800–1803 by CN. The locomotives were conceived by MLW as a way to use the 12-cylinder 244 diesel engines removed from MLW FPA-2s that were receiving the more-capable Alco 251 engine (making them similar to the MLW FPA-4 locomotive).
The Alco 244H engine is also known as the Alco 250 engine. This was done by Alco to disassociate the 250 from the troublesome 244 engine. The 250 was produced for a short time from 1955 into 1956. It was also used as a standard to rebuild older 244 engines at Schenectady. In 1949, in the midst of continued failures of 244 engines, ALCO ...
